JOINT FOR BOXES.

SPECIFICATION forming part of Letters Patent No. 372,694, dated November8, 1887.

Application filed August 15, 1887. Serial No. 247,036. (No model.)

To all whom it may concern.-

Be it known that l, LUDWIG F. MERoo'rT, of the city of Newark, in thecounty of Essex and State of New Jersey, have invented certain- I newand useful Improved Joints for Boxes; and I do hereby declare that thefollowing is a full, clear, and exact description of my invention,reference being had to the accompanying drawings and the letters ofreference marked thereon, which form a part of this specification.

For a more perfect understanding of my invention and its objects, I willstate that here tofore joints for boxes were made in such a manner thatsome portion of the cross-cut rough surface appeared, except whenthejoint is made as shown in Figure 5; but joints made in that mannerare ditlicult to construct, requiring some considerable care, a separatetenon, and a pressure from four sides while the glue is setting; andalso except when the joint is made as detailed in Patent No. 171,326,granted to George S Stearns; but joints made in that manner areobjectionable, because one side of the box must be twice the thickness,at least, of the corresponding end, or vice versa, in order to avoid theappearance of the cross-cut rough surface of the wood, and because,also,the dovetail tongue and groove are more ditficult toconstruct and put together and the glue is scraped off in uniting thecor- 11ers.

To avoid these several objections is the object of my invention.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe themanner in which the same is or may be made, referring to the annexeddrawings, in which-- Fig. 1 is the top view of the box, showing exactlyhow the different pieces are sawed or cut, and how they are united andjoined one to the other. Fig. 2 shows the two sides as they are about tobe united, forming thejoint lock or corner. Fig. 3 represents the cornerof the box when joined, showing a complete smooth surface, the grain ofthe wood meeting, and no cross cut rough surface appearing. Fig. 4 is aview of two parts joined together. Fig. 5 is a view of the old form ofjoint referred to.

The shapes D, E, and F are made to match with exactness the oppositeshapes, A, B, and C. The parts 0 E are female parts and the parts F Bare male parts. D and A are miters. These shapes, as described, can bemade smaller or larger to suit the thickness of the material used. Theshapes A, B, O, D, E, and F can be made on an ordinary circular-sawtable, either with circular saws shaped and adjusted in a suitablemanner or with shap- -ing-knives.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

A new, useful, and improved joint for boxes, having the female part 0,the male part B, and the miter A, in combination with the other sidehaving the male part F, the female part E, and the miter D.

In witness whereof I have hereunto set my hand in the presence of twosubscribing witnesscs.
